Hi Guys,

I'm confusing myself a little over hertz. I live in New Zealand, which is a 50hz country. Unfortunately, video lighting is extremely expensive over here and difficult to source so I've thought about buying fixtures from online US shops.

What I want to know is, are all the fixtures from professional lighting companies such as Arri 50/60hz compatible. I know the bulbs are different and I would need to use 50hz bulbs, but are the fixtures themselves a problem if I buy from the US?

Thanks to anyone who can help. As you can see I'm not a wizard in the electrical department.

Mains frequency is only a problem with fluorescent lights or HMI lights not fitted with a flicker free ballast.

For tungsten lights this isn't an issue unless you're shooting extreme slow motion, where you want the larger wattage (1k +) because the smaller units can show flicker when shooting at the higher frame rates.

The voltage is important, so you need to have the correct voltage lamps fitted.

Cheers Brian, nice clear explanation ;-)
